My heart goes out to her family and friends and to everyone who loved and cared about her. We have all been hit with a lightning bolt.”

Law enforcement sources said Ms. White, 28, died from a prescription drug overdose, TMZ reported. Two of her friends reportedly found her lifeless body after going to check on her.

On the day of the alleged breakup, Ms. Whitetweeted: “Signing off Twitter, I hope I have been a light to my nearest and dearest.”

The couple reportedly met in 2012, dated a few months and then split. They rekindled their relationship in May, TMZ reported.
